STATE BOARD OF HEALTH ON MALARIA 159 



indicate that these counties are hopelessly undesirable 

 sections of the State to live in, but to prove beyond 

 question that there is great need for centering a well- 

 organized, persistent fight against malaria in these 

 three areas. The object of the writer is to show the 

 financial loss now being sustained and to illustrate 

 clearly the importance of supporting the excellent work 

 done during the past year. 



"During 1910 three anti-mosquito organizations be- 

 gan work, with headquarters in Oroville (Butte County), 

 Penryn (Placer County), and Bakersfield (Kern County). 

 These organizations are described elsewhere in this 

 book, but their significance to California's future 

 deserves emphasis. In mere money values their success 

 means the saving of upwards of $500,000 annually 

 to each of the first two areas, $225,000 annually to 

 the third one, and ultimately over $2,250,000 a year 

 to the entire State. 



"These organizations need money and the personal 

 cooperation of every landowner in these districts. 

 Their first work is educational. There are many 

 residents of California who do not know that the 

 prevalence of a special kind of mosquito in these dis- 

 tricts is responsible for the losses and suffering caused 

 by malaria. They must be taught that the malaria- 

 bearing mosquito offers a vulnerable point of attack 

 upon this disease, because this mosquito alone serves 

 as the carrier of the malaria parasite from the blood 

 of the person who has the disease to the blood of other 

 persons who do not have it until bitten."
